Elves invade, I live broadcast travel to revitalize the gym

"Then, can we detect the origin of that energy?" Captain Mu asked.

"Well, the detector has a little reaction. It should be a little deeper."

The two moved on. Time was running out, and they were moving quickly in the cave with the help of Yongjira's flash.

"Dr. Xin, do you feel... here..."

"It seems like it's wrapped in something?"

Captain Mu said.

"Huh?" Mr. Xin was a little strange.

"This place was originally inside a cave... the outside should be something like a rock wall, right?"

"No, that's not right." Captain Mu shook his head.

"Our special operations team discovered the original stone of the Fire Stone in the volcano. Therefore, I often go in and out of the volcano with my team members."

"This place, this circle around this ruin, always feels familiar to me."

"It's like... it's like the rock wall of a volcano."

Captain Mu expressed his guess.

"volcano?"

Mr. Xin was startled. "You mean, this is a city built in a crater?"

"Hmm...it's really possible. If that's the case, the reason why this ruin can still exist instead of being buried directly may be precisely because of this..."

"Because it was built in a volcanic crater, when it was buried under the sea, the original volcanic crater formed a hollow cave, preserving everything here..."

"It's just that what happened and how long it took for a city to be buried tens of thousands of meters deep under the sea..."

Mr. Xin frowned and thought.

"Come on!" the suction cup golem suddenly shouted.

"What? Huh? The detector responded?" Mr. Xin was shocked.

"Captain Mu, please go in that direction!"

"Got it. Wind Speed ​​Dog!"

Captain Mu immediately adjusted his direction, and the wind speed dog flew towards the place where the detector detected the reaction.

In the blink of an eye, the two of them had reached the edge of the cave.

Mr. Xin looked confused: "Isn't this an ordinary rock wall... Is the abnormal energy inside the rock wall?"

The two of them didn't have much time, how could they possibly dig through such a solid rock wall...

"Wind Speed ​​Dog, did you find anything?"

The wind speed dog sniffed up and down the rock wall. Captain Mu immediately realized something was wrong.

"Woof!

"

Sensing Feng Su Gou's inquiry, Captain Mu nodded to Feng Su Gou. With the permission of the trainer, Wind Speed ​​Dog directly turned its head and pointed at a rock wall, and then suddenly sprayed out flames!

"This... is this place?"

The flames burned down a layer of floating soil. The true appearance on the rock wall was revealed.

"This...this is..."

"The door to the rock?"

Captain Mu was shocked again.

"Based on the location, this place should be on the volcanic wall."

Mr. Xin looked around.

"This should be a 'ruin' hidden in the mountain wall. Maybe it was built by people in the city, or maybe it's earlier than that city..."

He tried to push the door hard, and the rock door trembled slightly, and a lot of fine sand fell.

"It seems that it can be opened directly... let's go in and take a look!"

The two of them pushed open the door together, revealing a small stone room inside. In the stone room, a stone slab was quietly embedded in the wall opposite the door.

"Yes! That's it." Mr. Xin said in surprise.

"That energy should be this stone slab."

As he said that, he wanted to step forward and pry the stone slab off.

"Wait, Dr. Xin!" Captain Mu grabbed the excited Mr. Xin.

"Is there something..."

Mr. Xin was stunned. Only then did he notice that the suction cup demon next to him looked anxious. The wind speed dog next to Captain Mu also lay on the ground and purred alertly.

"Here? Is there danger? How could there be biological energy..."

Before Mr. Xin could finish speaking, the sound of something cracking suddenly reached his ears.

"Is it ice? Is there something..."

Several people looked above where the sound came from, but they only had time to see a red light, and then, there was a loud roar.

"Roar!

!

"

"Then...that red light is!"

Captain Mu was inexplicably horrified.

But there was no time for her to think about it. A huge body blocked the stone slab, and then there was a huge wave.

"This... what kind of skill is this!

! ”

The big wave swept the two of them out of the stone room. Captain Mu saw a blue elf with two long sharp teeth in the huge wave, tightly biting the wind speed dog washed by the big wave.

"What kind of elf is this!"

Being in the deep sea, the illustrated book cannot connect to Dr. Mu's database, so Captain Mu naturally doesn't know what this elf is.

If Lin Yu were here, he could tell her that this was the water and ice elf, the Diya Sea Lion!

"Wind Speed ​​Dog!"

After taking a "surf" move and being directly attacked by Frozen Fang, Wind Speed ​​Dog was already dying. Captain Mu finally managed to stabilize his body and quickly took out another elf ball.

"Please! Thundermon!"

"Roar!"

A majestic dog-shaped elf appeared in the red light. Different from Lin Yu's calling dog, this thunder beast is a majestic large dog that looks more calm and reliable.

"Thunder Beast! Thunder!"

"Roar!

! ”

Captain Mu directly used all his strength, and the thunder beast roared, and the abundant electric energy condensed into violent thunder, and crashed towards the emperor's tooth sea lion.

While the Diya Sea Lion was struck by thunder, Captain Mu rolled and collected the Wind Speed ​​Dog into the ball.

However, when the thunder light dissipated, the Diya sea lion actually formed a thick wall of ice, blocking the thunder beast's full blow!

"How...how is it possible!"

Captain Mu panicked. Her thunder beast has also been carefully cultivated. I can't say that it is better than the elf of Hall Master Xiao Yu, but compared with all other trainers, she is still very confident.

However, it was easily blocked by this elf!

"This elf... is so powerful!

"

In terms of strength, he is definitely the best among all opponents!

Facing this elf, Captain Mu suddenly felt like facing an opponent of Lin Yu's level.

"Guh...it's difficult..." Cold sweat broke out on Captain Mu's forehead.

This elf is so powerful, let alone defeat him. As long as it delays it for a while and misses the time, both myself and Dr. Xin, who are trapped deep under the sea, will definitely die.

"And... I don't know where Dr. Xin went..."

"Roar!

! ”

The Diya sea lion roared again. This time, a terrible cold wind blew across the entire venue.

The storm was mixed with blizzard, freezing the surrounding area at a speed visible to the naked eye.

"This... what kind of skill is this!"

If Lin Yu were here, he would be able to recognize that this is one of the strongest skills of the ice system, blizzard!
